Serialization of FQNs' metadata was broken - we attempted to serialiaze concrete modules and that's against the design.
Added a test illustrating the problem which would previously fail during serialization.
Closes#5037
# Important Notes
It is still hard to discover problems like this because SerializationManager creates system threads; when the exception occurs, it is typically not the real cause. Creating regular threads via `createThread` seems to be problematic for `native-image`. There is a simple workaround for the former but will leave it out for another PR to simplify the review.
Add `Comparator` type class emulation for all types. Migrate all the types in stdlib to this new `Comparator` API. The main documentation is in `Ordering.enso`.

- https://www.pivotaltracker.com/story/show/183958734
- https://www.pivotaltracker.com/story/show/184380208
# Important Notes
- The new Comparator API forces users to specify both `equals` and `hash` methods on their custom comparators.
- All the `compare_to` overrides were replaced by definition of a custom _ordered_ comparator.
- All the call sites of `x.compare_to y` method were replaced with `Ordering.compare x y`.
- `Ordering.compare` is essentially a shortcut for `Comparable.from x . compare x y`.
- The default comparator for `Any` is `Default_Unordered_Comparator`, which just forwards to the builtin `EqualsNode` and `HashCodeNode` nodes.
- For `x`, one can get its hash with `Comparable.from x . hash x`.
- This makes `hash` as _hidden_ as possible. There are no other public methods to get a hash code of an object.
- Comparing `x` and `y` can be done either by `Ordering.compare x y` or `Comparable.from x . compare x y` instead of `x.compare_to y`.
An exception encountered during serialization prevents engine from continuing because it enters an infinite loop(!).
# Important Notes
The aim of this PR is to make it possible for engine to recover from the serialization failures. Any failure would mean that we enter an infinite loop in deserialization which is in turn waiting for the serialization to finish (which will never happen).
In this particular case FQNs are [referencing concrete modules](https://github.com/enso-org/enso/issues/5037). A separate PR will address that.
Expressions returning polyglot values were not reporting the type of the result because we have to do additional magic that infers the correct Enso type. Since this is exactly what `TypeOfNode` does, I re-used the logic.
Straightforward solution failed in tests because of assertions:
```
[enso] WARNING: Execution of function main failed (Invalid library usage. Cached library must be adopted by a RootNode before it is executed.).
java.lang.AssertionError: Invalid library usage. Cached library must be adopted by a RootNode before it is executed.
```
That is why this PR replaces `ExecutionEventListener` with `ExecutionEventNodeFactory`.
# Important Notes
Usage of `TypeOfNode` for programs that **do not** import stdlib means that we report types that do not involve stdlib e.g.
`Standard.Builtins.Main.Integer` instead of `Standard.Base.Data.Numbers.Integer`. While surprising, this is correct and I would say desirable. While reviewing the code, notice the difference in expectations in our runtime tests.
- Fixes the display of Date, Time_Of_Day and Date_Time so doesn't wrap.
- Adjust serialization of large integer values for JS and display within table.
- Workaround for issue with using `.lines` in the Table (new bug filed).
- Disabled warning on no specified `separator` on `Concatenate`.
Does not include fix for aggregation on integer values outside of `long` range.
Before, any failures of the Rust-side of the parser build would be swallowed by sbt, for example if I add gibberish to the Rust code I will get:
<img width="474" alt="image" src="https://user-images.githubusercontent.com/1436948/217374050-fd9ddaca-136c-459e-932e-c4b9e630d610.png">
This is problematic, because when users are compiling in SBT they may get confusing errors about Java files not being found whereas the true cause is hard to track down because it is somewhere deep in the logs. We've run into this silent failure when setting up SBT builds together with @GregoryTravis today.
I suggest to change it so that once cargo fails, the build is failed with a helpful message - this way it will be easier to track down the issues.
With these changes we get:
<img width="802" alt="image" src="https://user-images.githubusercontent.com/1436948/217374531-707ae348-4c55-4d62-9a86-93850ad8086b.png">
Closes#5036
Move the logic that looks up method pointers from the language server to IDE. This way we can keep the suggestion updates and expression updates async, otherwise it will hurt the initial startup time of LS.
Fixes the issue when some expression updates does not contain the method pointer.
Follow up on
16ba57d465 which marked the tests as flaky.
This test goes back to the original implementation where JGit did all its book-keeping synchronously. When we switched to asynchronous operation, cleaning up the test directory would sometimes not succeed because there would be a race-condition with the ongoing work of JGit.
# Important Notes
In the current setup tagging a test as flaky is only valid for Windows. The other platforms ignore the flag. So we were still getting random failures.
Closes#5038
- Use the proper widget structure.
- Provide new method `get_widget_json` with whole structure, but keep `get_full_annotations_json` in old form.
- Start to get to some reusable functions.
- Added widget to JS_Object field selections.
Start `project-manager` with following options to provide first 20s of the startup sequence:
```
$ project-manager --profiling-events-log-path=start.log --profiling-path=start.npss --profiling-time=20
```
once the `start.log` and `start.npss` files are generated (next to each other), open them in GraalVM's VisualVM:
```
$ graalvm/bin/jvisualvm --openfile start.npss
```
analyze.
Implementation of https://www.pivotaltracker.com/story/show/184012743https://user-images.githubusercontent.com/919491/214082311-cf49e43c-1d1f-4654-903c-a4224cd954d8.mp4
This is also a step towards more general widget support. The widget metadata is queried using `Meta.get_annotation` method through a dedicated visualization. For now only `Single_Choice` case is handled, and always all suggestions are is returned.
# Important Notes
There are limitations as to which node segments receive a widget. Only chain method calls are supported now (`thing.method` syntax), and only outside of lambda scope. Widgets in lambdas will require support for visualisations of lambda subexpressions, which is currently missing in the engine. The IDE technically tries to place the widgets there, but the data never arrives. It should work once the engine support is added.
This PR includes a mock for `Meta.get_annotation` call that only supports `Table.at` method. Real implementation is a separate task that is already in progress.
JGit ops generally run fast (as in a few milliseconds) except for the first commit. The initialization + first commit was taking at least 3.5 seconds constistenly, but only in the first test case. Now, this led to frequent timeouts down the chain when the request was expected to finish fast.
The bookkeeping involved some timestamping and other expensive calls in order to calculate clock drift. The default appears to be to run it in a blocking mode, hence adding at least 3 seconds to the first command call.
Setting the job to run in the background makes the cost of the repo initialization acceptable (~300 milliseconds on a cold JVM). The other commands are unaffected and take < 10 milliseconds.
# Important Notes
Added a test to ensure that we don't introduce the regression. Marked it as potentially flaky because it uses timestamps and it is therefore prone to random system hiccups.
This PR aims to fix current issues with cloud IDE.
1. Backend image:
* bumping the system version to avoid glibc version mismatch on parser;
* explicitly installing required GraalVM components;
2. Frontend upload:
* update to follow the new file naming;
* uploading the whole shaders subtree.
This PR contains the first implementation of `cached_shape!` macro, which should help us with reducing draw calls in our application.
```rust
mod icon1 {
use super::*;
ensogl_core::cached_shape! { 32 x 32;
() {
let shape = Circle(16.px()).fill(color::Rgba::green());
shape.into()
}
}
}
mod icon2 {
use super::*;
ensogl_core::cached_shape! { 202 x 312;
() {
let shape = Rect((200.px(), 310.px())).fill(color::Rgba::red());
shape.into()
}
}
}
```
The above code creates two cached shapes. They are similar to normal shapes (created with `shape!` macro), except that:
1. they do not allow for any parametrization
2. They are rendered at the application start to the special texture with cached shapes.
The texture will be used in next PRs to cache all Component Browser icons on the texture and draw all of them just by single, fast draw call. In the future, more shapes can be cached, further reducing draw calls and making them simple.
# Important Notes
The results are presented in `cached_shapes` debug scene: there are two shapes displayed and a scaled cached texture is displayed in the background.
There is no need for JGit to try to save file attributes to its config in `<home>/jgit/config`. This change ensures that JGit operates on a stub file, without polluting users' configs, similarly to user's git config.
Additionally, noticed that all FS operations during `init` are rather slow and saw at least on one occassion when the handler timed out because of that (https://www.pivotaltracker.com/story/show/184359934). This change provides an init-specific timeout for `vcs/init`.
# Important Notes
This change should reduce chances of failures during VCS initialization.
- New `set` function design - takes a `Column` and works with that more easily and supports control of `Set_Mode`.
- New simple `parse` API on `Column`.
- Separated expression support for `filter` to new `filter_by_expression` on `Table`.
- New `compute` function allowing creation of a column from an expression.
- Added case sensitivity argument to `Column` based on `starts_with`, `ends_with` and `contains`.
- Added case sensitivity argument to `Filter_Condition` for `Starts_With`, `Ends_With`, `Contains` and `Not_Contains`.
- Fixed the issue in JS Table visualisation where JavaScript date was incorrectly set.
- Some dynamic dropdown expressions - experimenting with ways to use them.
- Fixed issue with `.pretty` that wasn't escaping `\`.
- Changed default Postgres DB to `postgres`.
- Fixed SQLite support for starts_with, ends_with and contains to be consistent (using GLOB not LIKE).
When a large long would be passed to a host call expecting a double, it would crash with a
```
Cannot convert '<some long>'(language: Java, type: java.lang.Long) to Java type 'double': Invalid or lossy primitive coercion
```
That is unlikely to be expected by users. It also came up in the Statistics examples during Sum. One could workaround it by forcing the conversion manually with `.to_decimal` but it is not a permanent solution.
Instead this change adds a custom type mapping from Long to Double that will do it behind the scenes with no user interaction. The mapping kicks in only for really large longs.
# Important Notes
Note that the _safe_ range is hardcoded in Truffle and it is not accessible in enso packages. Therefore a simple c&p for that max safe long value was necessary.
The new jgit integration tries to create config file in ~/.config/jgit/config. We are creating default ensodev with explicit `-M, --no-create-home`. As long as there wasn't any strong reasoning behind that this commit changes it to fix problems with initialising jgit.

In order to investigate `engine/language-server` project, I need to be able to open its sources in IGV and NetBeans.
# Important Notes
By adding same Java source (this time `package-info.java`) and compiling with our Frgaal compiler the necessary `.enso-sources*` files are generated for `engine/language-server` and then the `enso4igv` plugin can open them and properly understand their compile settings.
In addition to that this PR enhances the _"logical view"_ presentation of the project by including all source roots found under `src/*/*`.
https://github.com/enso-org/enso/pull/3764 introduced static wrappers for instance methods. Except it had a limitation to only be allowed for types with at least a single constructor.
That excluded builtin types as well which, by default, don't have them. This limitation is problematic for Array/Vector consolidation and makes builtin types somehow second-citizens.
This change lifts the limitation for builtin types only. Note that we do want to share the implementation of the generated builtin methods. At the same time due to the additional argument we have to adjust the starting index of the arguments.
This change avoids messing with the existing dispatch logic, to avoid unnecessary complexity.
As a result it is now possible to call builtin types' instance methods, statically:
```
arr = Array.new_1 42
Array.length arr
```
That would previously lead to missing method exception in runtime.
# Important Notes
The only exception is `Nothing`. Primarily because it requires `Nothing` to have a proper eigentype (`Nothing.type`) which would messed up a lot of existing logic for no obvious benefit (no more calling of `foo=Nothing` in parameters being one example).
For graying out the nodes, the engine need to send IDE a set of values that will be computed before executing the program (and the IDE colors them gray). In general, it is tricky to do because we cannot know for sure which exactly nodes will be computed without running the program. But we can estimate based on the invalidated values, which nodes are expected to be executed during the next run, and send them to the IDE. This logic is simpler than the previous approach, and turned out working pretty well in practice.
